The Centers for Disease Control and Prevention (CDC) and health authorities in CaliforniaLinked to newly discovered variants An individual who recently returned from South Africa tested positive for the strain in the United States on Wednesday.
The traveler has been fully vaccinated, has experienced “improving mild symptoms” and has been self-quarantining since the positive test, the CDC said. statement.. The person’s close contact has been contacted by health authorities and has been tested negative.
Health agencies have stated that the emergence of variants is “vaccination, booster immunization, and General preventive strategies Required to protect against COVID-19. Everyone over 5 years old should get a vaccinated booster Recommended for everyone over 18 years old. “
Since South African health officials, the United States has joined more than 20 countries and territories and has found cases of at least one strain worldwide. Classification Omicron as a “variant of concern” reflects the World Health Organization designation on holiday weekends.Over the variant on November 25th.Recent Biden administration
Dr. Anthony Fauci, the president’s chief medical adviser, told reporters at the White House briefing Wednesday that travelers were tested positive on November 29. The agency “is consistent with the Omicron variant.”
“This is the first confirmed case of COVID-19 caused by an Omicron variant detected in the United States. As you know, of course we are discussing this, but the first Omicron case was detected in the United States. It will be. ”
This discovery occurs when the Biden administration is considering stricter restrictions on overseas travel. This is part of a new strategy for controlling the virus that Biden plans to announce Thursday. The CDC has also stepped up efforts to monitor recent new cases of Omicron, including unplanned expansion of the pilot program.San Francisco International Airport.
CDC on Wednesday prior to the announcement Ordered The airline will begin handing over travel contact information for travelers from eight South African countries.
Fauci said he was unaware of the other potential cases of Omicron being investigated by the CDC in the country. He said Americans should continue to follow the CDC guidance to prevent the spread of variants, urging fully vaccinated people to “boost now” and additional doses provide some protection against variants. He said it was likely to bring.
“There are many reasons to believe that such an increase in boost will help prevent serious illnesses of mutants like at least Omicron,” he said. “You may not need a variant-specific boost. We are prepared for the possibility of a variant-specific boost.”
It remains unclear how accurately the vaccine works against the mutants. Omicron mutants share many mutations with other strains of concern, which may increase their infectivity and avoid the body’s defenses, but scientists risk the mutants in vitro. It warns that it may take several weeks to confirm.
Doctor at “Face the Nation” on Sunday.A former member of the Food and Drug Administration and a member of Pfizer’s board of directors, expressed confidence in the vaccine.
“People who watched this sequence carefully … those individuals are reasonably convinced that three doses of the vaccine are prophylactic,” Gottlieb said. “Now it may give a really strong impetus to try to boost more people.”
The emergence of the Omicron variant in the United States is in the midst of a busy vacation travel season. According to the Automotive Club AAA, it is estimated that more than 53 million Americans have traveled on Thanksgiving holidays, up from last year.
Food and Drug Administration To tell The current COVID-19 test may remain accurate in detecting subspecies infections, despite the habit known as “S-Gene Target Failure” that was also seen in previous strains. .. Some laboratories use it to prioritize positive tests that may be caused by Omicron for further gene sequencing to determine which mutant caused the infection. It states that it is.
Public health officials have defended US mutation monitoring efforts, claiming that the CDC-scaled public health and commercial lab system can detect new mutations. Prevalence up to 0.01% In the country.
CDC is now Estimate The Delta variant remains virtually all circulating viruses in the country.
